public class SimpleNodeConstructorFeed extends ItemFeed
The SimpleContentFeed is used when the node is constructed as a result of a computation on the streamed data,
for example xsl:value-of select="distinct-values(.//@price)". By contrast, a SimpleContentWatch
is used when the streamed nodes are selected directly, for example xsl:value-of select=".//@price".
Both a Feed and a Watch are needed because a simple content constructor operates on a sequence of nodes without simply atomizing the sequence.
